' tion of the same, reference being bad to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This inventlonrelates to that class of metallic wheels adapted to beconstructed wholly of sheet metalor metallic plates.

The object of the invention is to afford an exceedingly strong anddurable construction adapted for wheels of any size or for any serviceand in which comparatively narrow strips of metal are shearedlongitudinally and centrally toaiford for each strip a plurality ofradial spokesintegrally connected and diverging in pairs from the rim tothe ends of the hub.

It is finally an object of the invention to afford an exceedingly cheapconstruction and adapted to enable scraps from sheet metal to beutilized in wheel construction, if desired.

verse section of thesame.

The invention consists in the matters hereinafter described'and morefully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a side elevation of a wheel embodying myinvention. Fig. 2 is an enlarged, fragmentary, trans- Fig. 3 is anenlarged, perspective view showing. the slit strip after the same hasbeen bent and formed for insertion into the wheel. Fig. 4 'is asideelevation of the washer or clip whereby the spokes are rigidly securedto the hub sleeve. 7 f I As shown in the drawings: A indicates the rimwhich in the present instance, as shown, is a fiat rim though, ofcourse, it may be of any suitable type or construction to enable apneumatic tire to be'attached thereto if desired. The rim is constructedof a single strip of metal of suitable length, the ends of which arewelded or otherwisev secured together to afford a one piece rim,

and as shown, said rim is perforated transversely at intervals in itslength to aiford apertures corresponding in number with the number ofsets of spokes to be used. The

hub of the wheel B consists, as shown, of a tubular sleeve which alsomay be struckor rolled from sheet metal and as showmlls.

provided with a head 7), near each end thereof to afford a stop for thecollars or washers C, whereby the spokes are secured to the hub, saidbead acting to prevent said collars -in other words, acting'to hold saidcollars at the ends of thesleeve. The spokes consist of a strip of sheetmetal D, of approximately twice the radial distance from the sleeve tothe rim. This strip is'spl'it longior washers from being pressedinwardlyor tudinally to near the ends thereof and is bent centrally affording atthe bend an in wardly concaved portion d, and the webs on each side ofthe slit are sprung oppositely to afford two sets of divergent spokes d,which are connected at their rim extremities by the terminal unslittedportion of the webs, the

inner ends of the corresponding spokes ofeach set being connected bysaid concave bend d, as shown in Figs. 2 and 3.

The reduced ends d of said strip are then inserted through appropriateapertures in the rim A and may be riveted down as shown in Fig. 2, ormay bfielectrically or otherwise welded to the rim br braced thereto, ifpreferred, or connected therewith in any suitable manner to afford apermanent connection. The sleeve B is then inserted centrally and-theapertured washer or collar C is slipped over each end thereof and the peripheral flange 0 of said Washer 01: collar which is slitted to receivethe spokes therein is then. slipped onto each end 'ofthe sleeve with thespokes d lying in said slit and the bend cl coinciding with thecurvature of said flange between the slits and engaged above or restingon the bead 0 formed in the collar. A suitable press die, tool or anyappliance is applied to the hub sleeve and washers or collars eithersimultaneously or singly to upset the slightly protruding'end b of thehub sleeve to turn the same over the washer, to bend the collar beneaththe bent portion of the spokes, if the bead has not been previouslyformed and also to bend the inner edge of the peripheral flange of thewasher downwardly and inwardly, as shown in Fig. 2, to engage the loopor bend cl ,of the spokes firmly in place, in appropriate relation withthe hub sleeve. In closing the flange 0 inwardly any desired pressure ortension may be applied onthe spokes 'andinasmuch as the tool employedmay engage all parts of said flange at the same moment bending .the samesimultaneously inward, the pressure applied will obviously exert'equaltension on" said spokes, thereby very rigidly' securing'the hub sleeveand spokes together. Theoperation is obvious from the con:

struction described. I

course, sheet "or' plate metal of-any de-f s red gage may be employedfor the spokes,

for the rim and for the hub'sleeve and collars.' In any eventsheet'orplate metal of sufficient gage is employed for the collars,

or washers-to; insure the requisite strength. Such being the, case, itis obvious that wheels of any desired size and for any purpose may beconstructed as .de'scribed and.practically any required strength may 'bethus assured. 0f course, too, inasmuch as the'divergent spokes of eachpair are connected with the rim at the same point; an exceedingly strongand bracing construction is afforded insur ing great strength in;proportion to the weight of thewheeh While I have' 'show-n but, six setsof spokes, of-course by the construction-described any even number ofsets of spokes greater or less thanthis may cone veniently be employed.

Of course, I am aware that various modifications .may be made in-theconstruction described. However,.I have shown but one; of severalembodiments ofmyinvention and I therefore do not purpose limiting-thisap-' plication for patent otherwise sitated by the prior art..

I claim as myinvention: 1.1 In a device of the class a hub and flatmetallic spokes arranged with the width'ofthe metal directedlongitudithan necesnally with. theaxis of the rim to-Ires1st late'ralstrain and'a' collar on each lend of the hub provided with a bead and aflange, both of whichengag'e the hub ends of the spokes to afford. arigid connection between the spokes andl ub.
